Without the excellent cooperation of Yankee Atomic Electric Company, Connecticut Yankee Atomic Power Company, Battelle Columbus Laboratories, and Nuclear Materials and Equipment Corporation, this program would not be possible. Much of the credit for the success of the program is due Mr. James Tribble of the New England Electric System, Mr. Rudy Grube of Yankee Atomic Electric Company, and Mr, Owen Kruger of Battelle Columbus Laboratories. Special credit is also due Messrs. Bob Traggio and Wes Hartley of the Connecticut Yankee Atomic Power Company and Mr. Mel Bleiberg of Nuclear Materials and Equipment Corporation.
